Description
Technical Field
[0001] This utility model relates to the field of marine aquaculture, and in particular to a collection device for the Oriental seamstress clam. Background Technology
[0002] The Oriental seamstraw clam (Syngonium orientalis) belongs to the genus Syngonium in the family Syngonidae of the order Mandibulales in the phylum Bivalvia. In aquaculture, it is a type of attached fouling organism, often attaching to the surface of farmed species and facilities such as scallops and scallop cages, thus affecting the quality of life and yield of farmed scallops and oysters. However, the Oriental seamstraw clam is characterized by its small size, fragile shell, high calcium content, and high-quality protein in its muscle tissue, and in recent years has been found to be a high-quality feed for larval shrimp and crab farming. Currently, the main method of collecting Oriental seamstraw clams is to randomly drop old aquaculture nets into natural sea areas. However, this method suffers from poor standardization and mechanization. After collecting the clams, a large amount of manpower is required to remove the nets, and the inconsistent shape of the old nets and the small size of the clams make them difficult to separate.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0019] Combination Figures 1 to 3 As shown, this utility model discloses a collection device for *Clamus orientalis*, including a central shaft 1, a peeler 2, a lifting disc 3, and an attachment belt 4. The peeler 2 is sleeved at the end of the central shaft 1, and the inner diameter of the peeler 3 is slightly larger than that of the central shaft 1. The central shaft 1 is 2.5m to 3m long and 8cm to 10cm in diameter, with multiple chuck grooves 5 evenly spaced on it at intervals of 15cm to 20cm. The chuck grooves 5 are 5cm to 10cm long and approximately 6cm in diameter. The central shaft 1 is made of plastic, and the central shaft 1 and the chuck grooves 5 are integrally formed. Each chuck groove 5 is provided with a lifting disc 3, which is also made of plastic, making the device lightweight. The attachment belt 4 is made of 50-mesh nylon mesh and is generally long and narrow. One end of the attachment strip 4 is a fixed end, which is fixed to the bottom outer wall of the central shaft 1. The other end of the attachment strip 4 is a free end, which extends along the outer wall of the central shaft 1 through the peeler 2 to the chuck groove 5. A portion of the free end is located between the chuck groove 5 and the lifting plate 3, and the other portion covers the plate surface of the lifting plate 3.
[0020] In one embodiment, the lifting plate 3 includes a left half plate 31 and a right half plate 32, which are engaged to nest the lifting plate 3 within the clamping groove 5. Each of the left half plate 31 and the right half plate 32 includes a plate body 33 and a base 34, with the base 34 employing a mortise and tenon structure to achieve the engagement of the left half plate 31 and the right half plate 32. Designing the lifting plate 3 into two parts, with a mortise and tenon structure in the base 34, allows for quick installation and removal of the lifting plate 3, thereby enabling rapid binding and loosening of the attachment strap 4, saving time and costs. In a preferred embodiment, to further secure the lifting plate 3 and prevent it from falling off, a binding groove can also be provided on the base 34 for cable ties to further secure the left half plate 31 and the right half plate 32.
[0021] In one embodiment, a fixing hole 6 is provided on the bottom outer wall of the central shaft 1, and the fixing end of the attachment strip 4 is fixed in the fixing hole 6 by a pin. The pin is used to fix the fixing end of the attachment strip 4 on the one hand, and to prevent the peeler 2 from falling off the central shaft on the other hand.
[0022] In one embodiment, the free end of the attachment band 4 covers the surface of the support plate 3 and then extends further downwards along the circumference of the plate, spreading out in an umbrella shape. The plate 33 is used to horizontally support the attachment band 4. In traditional methods, the outer surface of the net cage is used to collect Oriental seamstress clam, but the surface area on the outer surface of the net cage where Oriental seamstress clam can attach is very limited. The plate 33 of this invention allows the attachment band 4 to fully extend in the horizontal direction, increasing the surface area for Oriental seamstress clam attachment. Furthermore, the attachment band 4 spreads out in an umbrella shape on the support plate, which greatly increases the area available for Oriental seamstress clam attachment and significantly increases the collection yield of Oriental seamstress clam.
[0023] In one embodiment, the peeler 2 includes a sleeve 21 and a peeling skirt 22. The sleeve 21 is nested on the central shaft 1, and the peeling skirt 22 is used to collect Oriental clams. In a preferred embodiment, the sleeve 21 has peeling skirts 22 at both ends. This ensures that the attachment band 4 is cleanly collected by the peeling skirts 22 during the collection of Oriental clams.
[0024] The method of using the collection device for Oriental seamstress clam of this invention is as follows: In late May each year, when the water temperature is around 10℃, the collection device for *Clamus orientalis* is deployed at a depth of 5-10 meters. Before deployment, the device is assembled: first, the fixed end of the attachment tape 4 is passed through the peeler 2, and then a pin is inserted into the fixing hole 6 at the bottom of the central shaft 1 to secure it to the central shaft 1. Then, the free end of the attachment tape 4 is stretched to the chuck groove 5, and wrapped around the left half 31 and right half 32 of the lifting disc 3. The left half 31 and right half 32 are then secured in the chuck groove 5, and further secured with cable ties through the binding groove. After securing one lifting disc, the attachment tape 4 is further stretched to the next chuck groove 5 on the central shaft 1, and the above operation is repeated. During deployment, multiple central shafts can be connected together with ropes. When wrapping the free end of the attachment tape 4, the purpose is to fix part of the free end in the chuck groove 5 and cover the lifting disc body for attaching *Clamus orientalis*; the wrapping method is not limited. For example, the free end of the attachment band 4 can be arranged in an "N" shape along the circumference of the chuck groove 5 and the lifting plate 4. Part of the "N" is consistent with the length of the chuck groove, and the other part extends from the lifting plate 3, or even hangs down from the lifting plate 3 in an umbrella shape.
[0025] After the collection device for *Sinonovacula orientalis* is deployed to the natural marine area where *Sinonovacula orientalis* grows in late May, it takes 3-4 months for collection. By August or September of the same year, the attachment strip 4 will be covered with *Sinonovacula orientalis*. At this time, the collection device (2.5-3m in length) is lifted from the sea by a winch on the ship and neatly arranged on the deck before being transported to the land-based production base for the removal of *Sinonovacula orientalis*. Before removal, the straps at the bottom of the lifting plate 3 are untied, and the lifting plate 3 is removed from the central shaft 1. At this time, the attachment strip 4 is in a loose state. Then, the pin is pulled out, separating the fixed end of the attachment strip 4 from the central shaft 1. The fixed end of the attachment strip 4 is pulled by mechanical power, and the fixed end of the attachment strip 4, along with the free end, is squeezed out between the peeler 2 and the central shaft 1. The *Sinonovacula orientalis* attached to the attachment strip 4 are left by the peeling skirt 22 of the peeler 2, thus completing the collection of *Sinonovacula orientalis*.
[0026] This utility model of the Oriental seamstress clam collection device greatly saves labor costs, collects very cleanly, reduces collection costs, and realizes the transformation of Oriental seamstress clam waste into treasure and standardized collection and utilization.
